Mohit spent Rs 12.75 on pencils and Rs 32.55 on books. If he had Rs 125 with him in the beginning, how much money is left with him after buying the items?

Answer

To solve the problem step by step, we will follow these calculations:

### Step 1: Identify the total money Mohit had initially.
Mohit started with Rs 125.

### Step 2: Identify the amounts spent on pencils and books.
- Mohit spent Rs 12.75 on pencils.
- Mohit spent Rs 32.55 on books.

### Step 3: Calculate the total amount spent.
To find the total amount spent, we need to add the amounts spent on pencils and books:
\[ \text{Total money spent} = \text{Money spent on pencils} + \text{Money spent on books} \]
\[ \text{Total money spent} = 12.75 + 32.55 \]

### Step 4: Perform the addition.
Align the numbers by the decimal point and add:
```
12.75
+ 32.55
--------
```
Starting from the right:
- 5 + 5 = 10 (write 0, carry over 1)
- 7 + 5 + 1 (carry) = 13 (write 3, carry over 1)
- 2 + 3 + 1 (carry) = 6
- 0 + 3 = 3

So, the total spent is:
\[ 12.75 + 32.55 = 45.30 \]

### Step 5: Calculate the remaining money.
Now, we subtract the total amount spent from the initial amount:
\[ \text{Money left} = \text{Initial money} - \text{Total money spent} \]
\[ \text{Money left} = 125 - 45.30 \]

### Step 6: Perform the subtraction.
Align the numbers by the decimal point and subtract:
```
125.00
- 45.30
--------
```
Starting from the right:
- 0 - 0 = 0
- 0 - 3 (we need to borrow, so it becomes 10 - 3 = 7)
- 4 (after borrowing, it becomes 4 - 5, we need to borrow again, so it becomes 14 - 5 = 9)
- 1 (after borrowing, it becomes 0 - 4, we need to borrow again, so it becomes 10 - 4 = 6)

So, the remaining money is:
\[ 125 - 45.30 = 79.70 \]

### Final Answer:
Mohit has Rs 79.70 left after buying the pencils and books.
